3 Claims. (Cl. 164-29) UNITED STATES PATENT oEFlcE Among the principalobjects which the present invention has in View are: To provide a pinkeddie for cutting collars or the like from blank strips of material; toprovide the collar blanks with pinked or notched edges; to prevent theedges of the collars from unraveling after being out from the strip ofmaterial; to provide means on the die whereby the collar blank afterbeing cut will not adhere to the die; to provide means for 105 operatingthe die; and to obtain other advantages and results as may be broughtout in the following description.

Drawing Figure 1 is a side elevation and partly in Section of a pressembodying my invention;

Figure 2 is a plan View of the bed with a strip o f blank materialattached thereto shown as taken on the line 2-2 of Figure l; f` Figure 3is a bottom planview of the die shown as taken on the line 3-3 of Figure1;

Figure 4 is a transverse sectional view of the die shown as taken on theline 4 4 of Figure 3;

and Figure 5 is a face view of a portion of the collar blank after ithas been cut by the die.

Description As seen in the drawing, I haveshown a press I0 having alowering carriage II, a slidable bed I2 and pivotal links I3 connectingsaid lowering carriage and the slidable bed. It is preferable that thelowering carriage and the slidable bed operate simultaneously, so thatas the bed is moved forward, the carriage will lower at the same time,

and having that operation in mind, I have provided a hand control meansin the form of a handle I4 suitably connected in any manner to the frontend of the slidable bed I2.

In carrying out the invention, I have provided a die I 5 shown assuitably mounted to the underside of the lowering carriage II beingmounted thereto by any suitable means, such as by bolts I6. Said die I5may be .suitably provided with downwardly directed cutting edges I1 sothat when coming in Contact with material from Which a collar blank isto be cut, the cutting edges will sever the material instantaneously andthereby provide uniform edges thereto.

The die I5 along the longitudinal cutting edge is provided with a pinkededge or a plurality of V-shaped notches I8 and shown as preferablyextending substantially on an arc from adjacent one end of the die toadjacent the other end,

beyond which the die terminates at each-end past the edge of the selvageas at I9. By virtue of the die extending beyond the selvage edge, itwill be noted that the corners or tips of a collar blank 2i! will haveno ragged or rough edges. Due

to the die cutting across the outer edge of the 5- selvage 2| sharpcorners are obtained and the material remains flat and may be readilyfolded producing the corner point of the collar whereby bulkiness willbe eliminated and at the same time the corner point will be reinforcedas shown and 10 described in rn'y co-pending application Serial No.749,190 filed October 20th, 1934. It will further be understood thatwhen cutting'a collar blank from a strip of material, the cutting edgeof the V-shaped notches I8 will cut the longitudinal arc-4 15' uate edgeof the collar from the one selvage corner portion to the other wherebysaid edge will have V-shaped notches 22, thereby preventing the threadsfrom deleteriously unraveling.

Extending inwardly at an angle from the op- 20 posite corners of the dieI5 is a transverse cutting edge 23, 23, which in practice may ybeutilized for cutting the throat portion 24 of the collar 20. It is to benoted that at the corner 25, said edge is at a more acute angle with theedge 2l than the 25 angular cutting edge 23, the purpose of Which is topermit cutting the selvages at a more acute angle. Said cutting edge 23likewise may be provided with a plurality of V-shaped notches 26preferably extending from the meeting point of 30 the more acute andless acute angles of the end edge, said notches extending along the edgeto approximately midway thereof. In this respect it will be furthernoted that one of said V-shaped notches preferably the one towards thecorner 35 25, is materially larger, as at 21, than the others, so thatwhen in practice the collar blank may be provided with an enlargedV.shaped notch 28 to be substantially the depth of the hem after theedges have been folded. 40

As seen in Figure 2, the bed I2 is substantially rectangular andprovides means for securely holding thereto a strip of material fromwhich the collar is to be cut. Such means may preferably be adjustablearms 29 detachably mounted 45 to the outside corners of the bed nextadjacent the blank position. Said arms Where attached to the bed areprovided with a slot 30 through which the Shanks of large-head bolts 3|pass into the bed. These arms may conveniently be adjusted 50 byloosening the bolts Whenever desired depending on the positioning of thestrip o-f material. On the extreme outer ends of the arms, pins 32 areprovided in an upstanding position and it is to these pins that theouter ends of the strip of 55 material are held securely to the bed. Athird upstanding pin 33 is attached to the bed itself and is positionedcentrally from end to end of the strip and slightly inward of onelongitudinal edge of said strip of material. However, when the bed withthe material thereon is moved inwardly towards the lowering carriage Ilwith the die l5, and as the material is being cut by the die, it is tobe understood that the said pins will in no Way interfere with thecutting operation, since it is preferable that the pins holding thematerial are clear of the die at all times.

In order that the collar blank may be held rmly While being cut, orotherwise should not adhere to the cutting edges Il vand 23 of the dieI5 after having been cut, I have provided cushioning means in the formof a substantially soft rubber 34 tted to the inside of the cuttingedges of the die along the entire cutting edges thereof. As more clearlyseen in Figures 1 and 4, the said .rubber protrudes slightly below thecutting edges. In practice and owing to the resiliency of the rubber, asthe die is lowered and the cutting edges sever the collar blank from thestrip of material, the rubber will contract under pressure so as not tointerfere with the cutting operation. However, as the lowering carriagestarts to raise and the die becomes disengaged after cutting thematerial, obviously then the rubber cushioning means will expand toagain protrude slightly 'below the cutting edges `il and 23, therebypreventing any of the material from accidently adhering to the die l5.

I I claim:

l. A die as characterized for cutting collar blanks and the like from astrip `of material, said die at its longitudinal edge having a pluralityof V-shaped cutting Vnotches and terminating to- Wards its outer endsthereby providing straight i cutting edges, and transverse V-shapedcutting notches at its transverse ends and terminating to- Wards itsouter transverse ends at an acute angle and substantially meeting theouter ends of said longitudinal straight cutting edges adapted to cutthe collar blanks from the strip of material thereby providing the cutcollar blank with V- shaped cut-out notches and straight corner edges.

2. A die as characterized for cutting collar blanks and the like from astrip of material, said die at its longitudinal edge having a pluralityof V-shaped cutting notches and terminating towards its outer endsthereby providing straight cutting edges, and transverse V-shapedcutting notches at its transverse ends and terminating towards its outertransverse ends at an acute angle and substantially meeting the outerends of said longitudinal straight cutting edges adapted to cut thecollar blanks from the strip of material thereby providing the cutcollar blank with V-shaped cut-out notches and straight corner edges,one of said notches at the transverse ends being deeper than adjacentnotches.

3. A die as characterized for cutting collar blanks and the like from astrip of woven material, said die providing longitudinal and transversecutting edges with said longitudinal cutting edge having a plurality ofarcuately disposed V-shaped notches extending adjacent one corner end toadjacent the other corner end, said longitudinal corner ends having asubstantially straight cutting edge, said transverse cutting edgeslikewise providing a plurality of V-shaped notches with one notchsubstantially larger than the others and terminating adjacent the endsnearest the said longitudinal straight cutting edges thereby providingsubstantially acute angular transverse straight cutting edges whereby incutting the collar blank the longitudinal and t ansverse edges areprovided with a plurality of V-shaped cut-out notches and the cornerswith straight edges.
